Tamiya 51742 TRF421 D Parts - Precision Suspension Arms for Track Performance  [51742]

Restore TRF421 stability with Tamiya suspension arms

The Tamiya 51742 TRF421 D Parts function as suspension arms intended to maintain the intended behaviour of the TRF421 chassis. They help keep suspension geometry true and steering consistent during competitive use.

Compatibility and fit

These arms are made to match the TRF421 mounting pattern and kinematic layout. Using the correct replacement parts helps preserve camber and steering characteristics across different setups.

Fitting guidance and inspection

Ensure correct torque on all fasteners and check that pivot points move freely after fitting. Regular inspections will catch early signs of wear so you can replace parts before performance drops.
